President Donald Trump has offered buyout packages to almost all federal workers who do not want to return to the office, a major move designed to shrink the US government.

In an email sent to millions of employees on Tuesday, his administration told workers they had to decide by 6 February whether they wanted to be part of a “deferred resignation program”.

If they agreed to leave their jobs by that date, the message said, they would receive about eight months of salary as a severance package. The Trump administration expects up to 10% of employees to accept the offer, or around 200,000 of the more than two million workers the federal government employs, according to the BBC’s US partner CBS News.
